feat(principles): principles.py turns the mechanical lenses into tool hits

principles.py runs ruff (C901, PLR0913, BLE001, S110, B006, B008, ARG), lizard (CCN, NLOC, parameters per function span) and jscpd (clones) on the lines a change touches and maps each hit to SRP, fail fast, KISS/YAGNI or DRY; a missing tool prints skip, every threshold is a required flag. It reuses the diff parsing of defaults.py, registered in sys.modules before it runs because dataclasses look the module up there, and hands lizard only the suffixes its 1.24.1 readers claim, since lizard parses any other file as C. kvb-code-clean step 3 calls it with McCabe's 10, pylint's 5 parameters, jscpd's 50 tokens and 50 NLOC; make install adds lizard 1.24.1 (pipx) and jscpd 5.4.2 (npm). The lizard and jscpd parsers are tested on fixture output only: neither tool has run for real yet.

+# Agent Instructions
+
+## Platform-agnostic development
+
+Everything in this repository MUST work on every agent runtime, not only on
+the one developing it: Claude Code, Codex, Gemini CLI, Hermes, OpenClaw and
+any other that reads skills. The same holds for operating systems and
+distributions.
+
+- **Logic in scripts**: behaviour lives in `python3` or `bash` scripts that
+  any runtime can call. Hooks, plugins and settings of one runtime are thin
+  adapters over those scripts, never the only path to a feature.
+- **Skills stay portable**: a `SKILL.md` that uses a runtime-specific tool
+  (`AskUserQuestion`, `SendMessage`, a slash command) says what the step
+  needs, so another runtime can use its own equivalent.
+- **Installs reach every runtime**: install into the cross-runtime locations
+  (`~/.agents/skills`) or through an installer that configures every
+  detected agent; runtime-specific locations are mirrors. Of a tool that
+  ships both, take the agent-agnostic integration over one runtime's plugin,
+  and never both: the same server would run twice.
+- **No single package manager**: an install never depends on one OS or
+  distribution's package manager; prefer upstream or statically linked
+  release builds.
+- **One instruction file**: rules live here and nowhere else; no
+  `CLAUDE.md`, `CLAUDE.local.md` or `GEMINI.md`. Claude Code reads this file
+  natively from v2.1.277; Gemini CLI once its `context.fileName` setting
+  lists `AGENTS.md`.
+
+## Code questions
+
+Ask the codebase-memory-mcp graph first (`search_graph`, `trace_path`,
+`get_architecture`); grep only after it.

 ## Naming 🏷️
 
-Every first-party skill is named `kvb-<category>-<name>` with one of these categories: `think`, `create`, `code`, `ci`, `git`, `check`, `org`, `skill`, `coach`. Only `kvb-cleanup`, `kvb-coach`, `kvb-help` and the collectors `kvb-dream`, `kvb-optimize` and `kvb-transcend` stand without a category. Names use `a-z`, `0-9` and single hyphens, at most 64 characters, and equal their directory name. `tests/test_naming.py` enforces all of it, including that the organigram below lists every skill under its category.
+Every first-party skill is named `kvb-<category>-<name>` with one of these categories: `think`, `create`, `code`, `ci`, `git`, `check`, `org`, `agent`, `skill`, `coach`: `think` thinks without producing a file, `create` produces an artifact, `code` works on code, `ci` on pipelines, `git` on history and forges, `check` analyses and reports findings, `org` coordinates agents, `agent` acts on one agent itself: its repository setup (code index, agent instructions) and its state (relax, sleep, wake up), `skill` works on skills themselves, `coach` serves the operator's wellbeing. Only `kvb-cleanup`, `kvb-coach`, `kvb-help` and the collectors `kvb-dream`, `kvb-optimize` and `kvb-transcend` stand without a category. Names use `a-z`, `0-9` and single hyphens, at most 64 characters, and equal their directory name. `tests/test_naming.py` enforces all of it, including that the organigram below lists every skill under its category.

The `kvb-org-radio` skill registers three hooks: its prompt hook delivers `broadcast` and `direct` items on the next prompt, a PostToolBatch hook delivers `security`, `pan-pan` and `mayday` items mid-turn, and an `asyncRewake` Stop hook wakes an idle session for a `mayday` or a `direct` item sent with `--wake`. The PreToolUse hook of the `kvb-org-queue` skill sends heavy commands through `queue.py hold` once the config sets `queue_enforce`. The global install also installs the MEDUSA security scanner with pipx for `kvb-check-security`, unless `medusa` is already on the PATH. Two hooks of the `kvb-org-perform` skill (`skills/kvb-org-perform/scripts/log.py`) log every Agent spawn with its task class, model and effort, and store the quality feedback a sandboxed session prints, in `~/.local/state/agents-council/subagent-model.jsonl`.

+description: >
+  Make a repository easy for agents: a code graph index (codebase-memory-mcp)
+  and lean agent instructions; kvb-optimize runs it.
+---
+
+An agent that queries a graph reads a fraction of what an agent exploring
+file by file reads, and short, current, consistent instructions get followed.
+This skill sets up the general code index,
+[codebase-memory-mcp](https://github.com/DeusData/codebase-memory-mcp) (MIT,
+fully local), and tightens the agent instructions of every repository in
+scope: the current one, or those `kvb-optimize` hands over.
+
+## Step 1: inventory
+
+`${CLAUDE_SKILL_DIR}/scripts/agents.py --repo <dir>` prints one line per
+check: AGENTS.md, any runtime-specific instruction file beside it, dead
+relative links in it, whether it names the index, whether the index binary is
+installed, and the state of the shared snapshot
+`.codebase-memory/graph.db.zst`.
+
+## Step 2: index
+
+- **Binary missing**: the skills repository's `make install` runs the
+  upstream installer, which installs the checksum-verified release (static
+  on Linux) into `~/.local/bin` and wires the graph into every agent it
+  detects (Claude Code, Codex, Gemini, Hermes, OpenClaw and more); rerunning
+  it updates. It writes the agents' configuration, so it is the operator's
+  step: hand `make install` to the `kvb-org-operator` skill and continue
+  after the restart.
+
+- **Index**: once installed, the skills repository's `make install` switches
+  `auto_index` on, so every repository a session opens is indexed and
+  watched; every skill that explores code asks the graph first. Check it with
+  `index_status`, index by hand with `index_repository` only where it is
+  missing, then `check_index_coverage`; every file kind it leaves out is a
+  finding.
+- **Snapshot**: ask whether the repository shares its graph. Shared: run
+  `index_repository` with `persistence: true` and commit
+  `.codebase-memory/graph.db.zst` at a fixed cadence (every commit of it adds
+  a full blob; Git LFS avoids that). Not shared: add `.codebase-memory/` to
+  `.gitignore`, and every agent indexes on its own.
+- **Domain graphs** the generic index cannot see, such as dependencies a
+  project declares in its own metadata, belong to the line that owns the
+  repository: record them as its task in the `kvb-org-rasci` register, never
+  build them here.
+
+## Step 3: instructions
+
+- AGENTS.md is the only instruction file: fold any `CLAUDE.md`,
+  `.claude/CLAUDE.md`, `CLAUDE.local.md` or `GEMINI.md` into it and remove
+  them. Claude Code reads AGENTS.md natively (v2.1.277+) but skips it while a
+  `CLAUDE.md` is on the path; Gemini CLI reads it once `context.fileName`
+  lists it.
+- AGENTS.md sends code questions to the graph first (`search_graph`,
+  `trace_path`, `get_architecture`) and to grep only after it.
+- `/claude-api prompt-audit` over AGENTS.md and the files it references finds
+  stale, duplicate and contradicting rules; the dead links of step 1 join its
+  findings.
+
+## Step 4: confirm
+
+One `AskUserQuestion` per improvement, `multiSelect: false`: the change, its
+evidence, and `Apply now`, `Record as a task`, `Skip`. No repository file
+changes before the answer, and nothing is committed.

+   for each `Monitor`).
+4. **Handover**: write `handover_night_<session id>.md` (the id in

+it saves, over 100 % it costs more. Paste the script's lines, never a
+paragraph about them. `<ref>` is the commit the change
+starts from: `HEAD` for uncommitted work, the merge base with the default

+
+## Skills: tokens
+
+```bash
+python3 ${CLAUDE_SKILL_DIR}/scripts/tokens.py --repo <skills repo> --base <ref> --transcripts ~/.claude/projects [--value <tokens/day> --evidence "<one line>"]

+
+It compares every changed `*.md` under `skills/`, untracked ones included,
+at `<ref>` with the working tree, and the always-loaded listing: all
+`description:` words, counted by the repository's `scripts/budget.py`.
+Tokens are an estimate, characters / 4. Changed files without any base text
+print `cost new`, which counts as over 100. Skills have no time.
+
+A second line, `💰 value 1:<n>` (`<n>:1` when value < cost), weighs both

+  changed `SKILL.md`'s tokens delta x its invocations, per day of the last
+  7 days' transcripts (other runtimes: JSONL of that shape). A new skill
+  takes its category's median, named in the line.
+- **Value**: tokens/day saved, derived by one `--evidence` line, e.g.
+  `"3829 SendMessage wakes/day x 10 % avoided x 43k"`; else `?:?`.

+
+Start it in the directory the command expects. It checks `<ref>` out as a
+detached worktree under `/tmp`, runs the command there and in the working
+tree from the same relative directory, compares CPU seconds and peak RSS,
+and removes the worktree. Cost is the mean of the CPU and the RAM ratio.
+It also measures wall time for `kvb-check-speed`.
+
+- **Runs**: one per tree. Both values at most 100 end it; otherwise 4 more
+  per tree, alternating, and the line reports the mean of all 5
+  (`mean of 5`).
+- **Other load**: a 1 s sample of system CPU busy before and after, and per
+  run the busy share beyond the command's own CPU time. Above 30 %, or
+  unreadable without `/proc/stat`, the result is an estimate: time comes
+  from the CPU-time ratio, both values carry `~` and the line ends in

+- Report the run you made; never rerun to pick the best result.

+## Exit codes
+
+- `0`: at most 100.
+- `3`: over 100, or new: pass the value to `kvb-check-score`; its gate asks

+- `2`: usage error, or the command failed; the message names the tree, the
+  exit code and the last stderr line. Fix the command, then measure.

+"""Measure a command's CPU seconds, peak RAM and wall time on a base ref and on the working tree.
+
+Args:
+    --base: git ref to compare with; checked out as a detached worktree under /tmp
+        and removed again, whatever happens.
+    --json: print the figures as JSON instead of the line.
+    -- <command...>: the command, run without a shell from the same directory
+        relative to each tree's root; its output is discarded.
+
+Runs:
+    One run per tree, base first. When cost and time are both at most 100 that
+    is the result; otherwise 4 more runs per tree, alternating, and the arithmetic mean
+    of all 5 per tree counts.
+
+Other load:
+    A 1 s /proc/stat sample of system CPU busy before and after the runs, and per run
+    the busy jiffies minus the command's own CPU time, as a share of all jiffies. When
+    any share exceeds 30 % or cannot be read, the result is an estimate: time comes
+    from the CPU-time ratio instead of wall time.
+
+Output:
+    `💸 cost <p> % (cpu <b>→<a> s, ram <b>→<a> MB) · ⏱️ time <p> % (wall <b>→<a> s)`,
+    then ` · mean of 5` after the extra runs. An estimate marks both values with `~`,
+    shows `(cpu <b>→<a> s)` for time and ends in `(estimated: other load <x> %)`, or
+    `unknown` for <x>. Cost is the mean of the CPU ratio (user plus system seconds
+    of the command and its waited-for children) and the peak RSS ratio; each ratio is
+    working tree over base, times 100.
+
+Exit codes:
+    0 cost and time at most 100, 2 usage error or a failing command
+    (its tree, exit code and last stderr line on stderr), 3 either over 100.

+description: >
+  Prove 90/5: every `make test*` target green on the exact HEAD. Trigger
+  before declaring 90/5 or labelling a PR, or on "gate status".
+---
+
+The gate rule, stated here and nowhere else: nothing is declared 90/5 (fix
+confidence ≥ 90 %, break risk ≤ 5 %, cost and time ≤ 100 % in
+`kvb-check-score`; over 100 %, ask the operator before the commit, naming
+the cause) before every `make test*` target of the project, each Makefile target named `test` or starting with
+`test-`, ran green on the exact head with a clean tracked tree. Until then
+the numbers are provisional and every target not green is a residual.
+
+`${CLAUDE_SKILL_DIR}/scripts/gate.py` reads the targets from the Makefile and
+its includes without running make, and keeps results per commit in
+`kvb-gate.json` in the git common dir: linked worktrees share them, a new
+commit starts from zero.
+
+## Steps
+
+1. **Sync**: `${CLAUDE_SKILL_DIR}/../kvb-git-hotfix/scripts/hotfix.py sync
+   --repo <root> --task <your register task>`, then `hotfix.py pending
+   --repo <root>`, by the `kvb-git-hotfix` skill. A merge moves HEAD, so the
+   gate starts over from there.
+2. **List**: `gate.py list --repo <root>`. A warning about an unresolved
+   include or target expression means the list may be short: read that line
+   and name the gap. A project without any target keeps the gate open; ask
+   the operator.
+3. **Status**: `gate.py status --repo <root>`. `gate: green` ends here; a
+   `missing hotfix` reason means back to step 1.
+4. **Admit**: every gate target is heavy and runs only inside
+   `${CLAUDE_SKILL_DIR}/../kvb-org-queue/scripts/queue.py hold` (step 5),
+   which grants by rule and releases on exit. Only a single test module
+   self-admits (`${CLAUDE_SKILL_DIR}/../kvb-org-organize/scripts/watch.py
+   admit --kind test-nostack`), and it never turns a gate target green. A
+   hotfix gate adds `--hotfix <slug>` and takes the next free gate slot.
+5. **Run** the missing and red targets, tracked tree clean, in the
+   background; give the operator `tail -f` on the log:
+
+   ```bash
+   queue.py hold --kind <kind> --task <register task> -- gate.py run --repo <root> --target <t> [--target ...] --log-dir /tmp/<slug> [--fail-regex <re> ...]
+   ```
+
+   Pass one `--fail-regex` per failure line the project prints while exiting
+   0; infinito-nexus needs `FAILED TARGETS: \S`. A non-zero exit, a
+   `make: ***` line, a matching regex or modified tracked files make a
+   target red; the last stops the run. Before each target `run` asks
+   `hotfix.py void` for it and every later one. Exit 3 (`void: merge main
+   for hotfix <slug>, then rerun`): back to step 1, then through the queue
+   again. Exit 75: the worktree is
+   busy, the message names the holder; wait, then rerun.
+6. **Judge** every red target by its `status` line and the log around it:
+   caused by the change, already red on the default branch, or the
+   environment. Fix the cause and rerun; looking unrelated never makes it
+   green.
+7. **Status** once more; its last line is the verdict.
+
+## Rules
+
+- Only `gate.py run` on this head marks a target green. A peer's report, CI,
+  an older commit or a dirty tree never does.
+- Every heavy command in a worktree (deploys, `make test`, other gates) runs
+  through `gate.py run` or `gate.py hold --repo <root> -- <command>` in the
+  background (`run_in_background`), never under a tool timeout or
+  `TaskStop`. Their lock keeps `hotfix.py sync` out
+  only while a host process under it lives; a `docker compose exec` deploy
+  runs on in its container unguarded.
+- 90/5 is allowed only on `gate: green` for the exact head: in
+  `kvb-check-score`, the `90/5` label and the `kvb-org-split` bar.
+- Never edit `kvb-gate.json` by hand.
+
+## Output
+
+| Target | Status | Log | Line |
+
+Then the `gate:` line verbatim.

+"""List, run and check a project's `make test*` targets against the current HEAD.
+
+Args:
+    list --repo <dir> [--json]: the Makefile targets named `test` or `test-*`,
+        parsed statically from the Makefile make reads in <dir> and every file
+        it includes; make is never run.
+    status --repo <dir> [--json]: per listed target green, red or missing for
+        HEAD, from `kvb-gate.json` in the git common dir; `hotfix.py pending
+        --target <t> ...` of the kvb-git-hotfix skill, given the listed
+        targets, keeps the gate open while a merged hotfix that turns one of
+        them green is missing from HEAD.
+    run --repo <dir> --target <t> [--target ...] --log-dir <dir>
+        [--fail-regex <re> ...]: under the worktree lock, run each target as
+        `make -C <dir> <t>` with stdout and stderr in
+        <log-dir>/gate-<t>-<sha8>.log and record the result for HEAD. A
+        target is red on a non-zero exit, a `make: ***` line, a matching
+        --fail-regex, or tracked files it modified. Before each target,
+        `hotfix.py void` decides over it and every target after it whether a
+        merged hotfix missing from HEAD voids the run.
+    hold --repo <dir> -- <command...>: under the worktree lock, run the
+        command in <dir> in a session of its own, without a controlling
+        terminal; SIGINT, SIGTERM and SIGHUP reaching hold go to the
+        command's process group while hold keeps waiting for it. For deploys
+        and every other heavy command that is no `make test*` target.
+
+    The worktree lock is `kvb-gate-run.lock` in the worktree's git dir,
+    taken without waiting and passed to make or the command, so it stays
+    held while they or a process they left running on this host live; a
+    process inside a container (`docker compose exec`) runs on there after
+    they die, and the lock no longer covers it. run and hold write their PID
+    and command into it, and a busy message names them. `hotfix.py sync`
+    takes `kvb-gate-sync.lock` exclusively, recording its PID and command
+    there, then the worktree lock, and releases them in reverse order; run
+    and hold take the worktree lock while holding `kvb-gate-sync.lock`
+    shared, so they wait for a running sync, naming it, for at most
+    SYNC_WAIT_SECONDS, and a busy worktree lock then means another run or
+    hold.
+
+    Without hotfix.py next to this skill, or when it exits non-zero without
+    a verdict line, gate.py warns on stderr and goes on without the hotfix
+    check.
+
+Output:
+    list: one `<target>\t<file>:<line>` per target.

+    run: one `<status>\t<target>\t<log>\t<reason>` per target; on a void
+        `void: merge main for hotfix <slug>, then rerun`.
+    hold: the command's own output.

+"""Report the principle-lens hits of ruff, lizard and jscpd on the lines a change touches.
+
+Args:
+    --repo: a directory inside the git work tree to scan.
+    --staged: scan only the staged changes (git diff --cached); the tools
+        read a snapshot of the index. Without it: every change against HEAD,
+        staged and unstaged, in the working tree.
+    --file: count every line of this file as changed; repeatable, relative
+        to --repo or absolute. Untracked files are in no diff.
+    --ccn: a function above this cyclomatic complexity is a hit (ruff C901,
+        lizard).
+    --nloc: a function above this many lines of code, blank and comment
+        lines excluded, is a hit (lizard).
+    --params: a function above this many parameters is a hit (ruff PLR0913,
+        lizard).
+    --min-tokens: a clone of at least this many tokens is a hit (jscpd).
+    --json: print the hits as a JSON list instead of tab-separated lines.
+
+Output:
+    One line per hit: file:line, lens, tool, message. ruff C901 and PLR0913
+    and lizard map to SRP; ruff BLE001, S110, B006 and B008 to fail fast;
+    ruff ARG to KISS/YAGNI; jscpd to DRY. A ruff hit counts when its range
+    touches a changed line, a lizard function when its span does, a jscpd
+    clone when either side does. ruff reads Python files, lizard the
+    languages it has a reader for, jscpd the whole tree for clone partners.
+    A tool missing from PATH writes `skip: <tool> missing` to stderr instead
+    of hits.
+
+Exit codes:
+    0 no hits, 1 hits, 2 usage error, git failure, a failed tool or
+    unreadable tool output, or a missing kvb-code-clean/scripts/defaults.py,
+    which parses the diff.

+Paste its two lines verbatim; they replace prose numbers.
+
+```bash
+python3 ${CLAUDE_SKILL_DIR}/scripts/score.py --fix <0-100> --break <0-100> --efficiency <n|-|new> --speed <n|-> --security <n|~n> --critical <count>

+| Emoji | Value | Source |
+| --- | --- | --- |
+| 🎯 | fix confidence | `kvb-check-confidence` |
+| 💥 | break risk | `kvb-check-break-risk` |
+| 💸 | cost, `--efficiency` | `tokens.py` (skills) or `measure.py` (code) of `kvb-check-efficiency` |
+| ⏱️ | time, `--speed` | `measure.py`, see `kvb-check-speed` |

+| 🏆 | score | this script |
+
+Cost and time: after over base in percent, over 100 worse. `-` means not
+measured or not relevant (skills have no time) and counts as
+100; it shows as `–`. `new` (changed skill text without a base) counts as 100
+in the score, yet still asks. Never invent a value: measure it or pass `-`.
+
+Score = `fix * (100 - break) / 100 * 100 / cost * 100 / time * security / 100`,
+capped to 0..100 and rounded.
+
+## Gate
+
+The second line is the verdict, first match wins:
+
+- `⛔ gate: critical security finding: do not commit` (exit 4): the commit
+  call is not sent, not even on an earlier approval. Fix the finding,
+  rescan, score again.
+- `⛔ gate: fix <f> % < 90` or `⛔ gate: break <b> % > 5` (exit 1): the 90/5
+  rule fails, which bars PR labels and the split bar, not a commit: show it
+  in the block and commit only on the operator's word. Close the gap as the
+  last section of `kvb-check-break-risk` says.
+- `⚠️ gate: <causes>: ask the operator before the commit` (exit 3), naming
+  each of `cost <c> % > 100`, `time <t> % > 100` and
+  `security <n> % < 100`: ask with the block what the cost buys or why each
+  finding is acceptable; commit only on a yes, never carried over to
+  another commit.
+- `✅ gate: 90/5, cost and time <= 100, security 100 %` (exit 0):
+  commit as usual. 90/5 still needs `gate: green` of `kvb-check-gate`.
+- Exit 2: usage error.
+
+## Tables and message block
+
+Each flag replaces the two lines; values, gate and exit code stay:
+
+- `--table`: one markdown table, `| 🎯 Fix | 💥 Break | 💸 Cost |
+  ⏱️ Time | 🛡️ Security | 🏆 Score | Gate |`.
+- `--commit-table <repo>`: that table led by `🌿 Branch | 📊 Diff stat`
+  from git, 📁 worktree path below, alone in a code block. Every commit
+  block is this table; after the commit, `--commit <sha>` shows that commit's diff stat
+  and a `🔖 Commit` column.
+- `--message-block`: one value per line, `🎯 Fix: <f> %` through
+  `🏆 Score: <n>` and `🚦 Gate: <verdict>`. Every commit message carries it
+  as its own paragraph right before the `Co-Authored-By` line, passed as one
+  `-m` argument, so the approval prompt and git history show the values.

+
+```bash

+```
+
+It copies the files changed since `<ref>`, untracked ones included and
+symlinks left out, to a temporary tree, scans it once with
+`medusa scan <tree> --format json -o <dir> --no-cache` and prints one line:
+`🛡️ security <n> % (medusa: <k> findings in <m> files: <severity> <path>:<line>, ...)`.
+`<n>` is 100 minus 50 per critical, 25 per high, 10 per medium and 2 per low
+finding, at least 0. It shows locations and counts only, never a matched
+value. Pass `<n>` as `--security` and the critical count as `--critical`
+(`--json` holds it) to `score.py`.
+
+- Exit 0: 100 %. Exit 3: below 100 without a critical finding; the score
+  gate asks the operator. Exit 1: a critical finding; the score gate forbids
+  the commit.
+- Exit 4: medusa is missing or its report unreadable. Review trust
+  boundaries, secrets and injection in the diff by hand, then pass
+  `--security '~<n>'` (quoted: zsh expands a bare `~100` as a user's home) and the critical findings you found as `--critical`.
+- Exit 2: usage error.
+- **Accepted false positives**: `security.py accept --repo <root> --rule
+  <id> --path <path> --sha1 <sha1> --reason "<one line>"`, rule, path and
+  sha1 from `--json`, appends a row outside the repository: to the council
+  root, which the `kvb-org-organize` watch hook keeps in
+  `~/.local/state/agents-council/`. A match leaves the score and shows as
+  `<a> accepted`; editing the line brings it back. Accept only after reading
+  the rule's pattern, and name each acceptance in the commit message.
+
 ## Rules
 
 - Run scans read-only; never pass `--reveal` and never run `medusa secrets purge` unless the user explicitly asks for it.

-   artifact path and nothing more; the assertion text, the server-side
-   exception and the state dumps are inside the artifact. Do this even when the
-   log looks conclusive, because a log that explains the symptom rarely
-   explains the cause.
-5. **One funnel per cluster.** Hand every cluster you claimed in step 3 to the
-   `kvb-org-split` skill: one agent per cluster, working in its own worktree on its own
-   branch created from the exact current HEAD, with that cluster as its only
-   concern, the artifact paths of step 4 in its brief and a time cap for its
-   interim report.
-   Steps 6 to 8 run inside that sidetree, so no cluster's edits land under
-   another cluster's work or under a running gate or deploy. Run clusters in
-   parallel only when their fixes touch different files and the machine has
-   room. A split cluster (step 7) gets a funnel of its own.
-6. **Dialectic per cluster.** For EACH cluster, invoke the `kvb-think-dialectic` skill:
-   form a thesis about the root cause from evidence (the job log, its artifacts,
-   the code at the run's commit, git history), attack it with independent
-   skeptics, and iterate to a ~99% thesis.
-7. **Distinguish shared vs hidden causes.** A cluster is a hypothesis, not a
-   proof: if the dialectic shows one cluster splitting into two causes, split it.
-   When a job hides a second failure behind the first, keep going until the job
-   is actually green, not just past the first error.
-8. **Fix at the root, through the funnel.** Apply the real fix for each proven
-   root cause in the cluster's sidetree, with a test and a negative control as
-   the `kvb-org-split` skill demands. The fix enters the main line only at the funnel's
-   bar (at least 90 % fix confidence, under 5 % break risk) after its
-   independent review; below the bar the cluster ends as a proposal for the
-   operator, never as a merge. Never mask a failure: no retry-until-pass, no
-   disabling the check, no soft-skip. If a failure is genuinely external
-   (upstream outage, flaky infra), confirm that with evidence and surface it
-   honestly instead of fixing around it. Report every fix, every proposal, and
-   every abandoned attempt to the same agents through the `kvb-org-organize` Peer protocol,
-   then remove the sidetree.
-9. **Tune what ran out of time.** Only for a cluster whose jobs died on their
-   time budget (timed out, or cancelled by the runner's limit), or when the
-   operator asks: hand the job log that ran furthest to the `kvb-code-tune` skill. Its
-   candidates run through funnels of their own, separate from the cluster's fix
-   sidetree, and never delay or block the fix.
-10. **Follow the run.** While the run is still in progress, re-check it
-   periodically and triage each newly failed job as it appears. The run is done
-   only when it has finished and every failure has a verified fix.

+Run inside the cluster's own worktree, so no cluster's edits land under
+another cluster's work or under a running gate or deploy. The `kvb-ci-triage`
+skill's Rules apply here too.
+
+1. **Dialectic**: invoke the `kvb-think-dialectic` skill for the cluster:
+   form a thesis about the root cause from evidence (the job log, its
+   artifacts, the code at the run's commit, git history), attack it with
+   independent skeptics, and iterate to a ~99% thesis.
+2. **Shared vs hidden causes**: a cluster is a hypothesis, not a proof; if
+   the dialectic shows it splitting into two causes, split it, and the new
+   cluster gets a funnel of its own. When a job hides a second failure behind
+   the first, keep going until the job is actually green, not just past the
+   first error.
+3. **Fix at the root**: apply the real fix for each proven root cause in the
+   sidetree, with a test and a negative control as the `kvb-org-split` skill
+   demands. Light runs (no Docker, about a minute: targeted pytest or
+   unittest, ruff, single lint files) self-admit with
+   `${CLAUDE_SKILL_DIR}/../kvb-org-organize/scripts/watch.py admit --kind
+   test-nostack`; `make test`, gates, deploys and anything with Docker run in
+   the background through
+   `${CLAUDE_SKILL_DIR}/../kvb-org-queue/scripts/queue.py hold --kind <kind>
+   --task <register task> -- <command>`, which waits for the rule-based
+   grant and releases on exit. The fix enters the main line only
+   at the funnel's bar (the `kvb-org-split` skill's: fix confidence ≥ 90 %,
+   break risk ≤ 5 %, cost and time ≤ 100 % in the `kvb-check-score`
+   block; over 100 %, ask the operator before the commit, naming the cause)
+   after its independent review; below the bar the cluster ends as a
+   proposal for the operator, never as a merge. Never mask a failure: no
+   retry-until-pass, no disabling the check, no soft-skip. If a failure is
+   genuinely external (upstream outage, flaky infra), confirm that with
+   evidence and surface it honestly instead of fixing around it. Report every
+   fix, proposal and abandoned attempt to the peers asked in step 3 of the
+   skill with `${CLAUDE_SKILL_DIR}/../kvb-org-radio/scripts/radio.py post
+   "<text>"` (`--to <name>` per peer), then remove the sidetree.

+# Run behind HEAD
+
+A CI run is a snapshot of one commit, and the branch has moved since. Scope
+the job set down **before** enumerating, clustering or spawning anything:
+every job investigated against stale code is work thrown away, and a fix
+proposed there risks reverting someone else's.
+
+Two cheap discriminators, without opening an artifact:
+
+- `git diff --name-only <run-sha>..HEAD -- <source dir> | cut -d/ -f2 | sort -u`
+  shows which components already moved.
+- A grep of the saved job logs for the literal error signature of each cause
+  already fixed in that range.
+
+What survives both is the job set the procedure applies to; say how many jobs
+you dropped and why. The run cannot contain a fix that landed after it, so
+looking only at its commit can only ever confirm the failure.

+First match wins: claimed by a peer, `keep`; in a register task not `done`,
-  sandbox or permission config (in Claude Code:
+`stopped` or `stale`, `keep (task <task>)` (an ended task's items are its

-  (`.X11-unix`, `.ICE-unix`, `systemd-private-*`, `ssh-*`, `tmux-*`, sockets)
+possibly in use)`; archive duty,
-  are never candidates.
+`archive first`, never a plain delete. Else a candidate:
-- **Docker**: `docker system df -v`; containers with state and compose project
-  label, volumes with the containers using them
-  (`docker ps -a --filter volume=<name>`), dangling and unused images, build
-  cache, unused networks. For every stopped container (`exited`, `created`)
-  record its volumes (`{{.Mounts}}`); for every volume no running container
-  uses, record size, `CreatedAt` (`docker volume inspect`) and compose project
-  label, anonymous ones included.
-- **Worktrees**: per worktree its size (`du -sh`), its dirty state (`git
-  status --short`), whether its branch is pushed, and whether its HEAD is
-  already contained in an integration line: the default branch and every
-  branch the project merges features into (ask the operator or the project's
-  memory which ones). With `pkgmgr` installed, `pkgmgr branch gc --json
-  --sizes --merged-into <line>` (one per line) measures all of it; its
-  merged-clean items go to the `kvb-git-branch-gc` skill.
-- **Other agent dirs**: package and tool caches (pip, npm, pre-commit, act,
-  gh, buildx), Ansible and build temp dirs.
-- **Register**: `rasci.py artifacts` of the `kvb-org-artefacts` skill:
-  workdir, branch and artifacts of every task in the `kvb-org-rasci` register,
-  with its status and worker; `--ended` narrows it to the candidates.
-- **Live use**: open handles (`fuser`, `lsof`) and running processes by name
-  only (`ps -o pid,etime,comm`). Never print full command lines or
-  environments: process arguments carry credentials. A sandboxed agent often
-  sees only its own processes, so an empty handle list proves nothing there;
-  then only entries untouched for more than 24 hours (`find -mtime +0`) are
-  candidates, and newer ones stay as `keep (recent, possibly in use)`.
-- **Archive duties**: memory and project instructions that require copying
-  something out before deletion (logs, reports, generated maps). Such an item
-  is `archive first`, never a plain delete.

-   `keep (task <task>)`. Under an ended task it is a candidate whose owner is
-   the task's worker.
-3. A job running on it (deploy, gate, test, swarm run, build): `keep
-   (running)`.
-4. Attributable to a peer that has not answered: `keep (no answer from
-   <peer>)`. Silence is not consent.
-5. Archive duty: `archive first`.
-6. Everything else is a candidate with a risk class:
-
-| Risk | Meaning | Typical items |
-| ---- | ------- | ------------- |
-| low | regenerated automatically, cheap | stopped containers without volumes, dangling images, unused networks, scratch dirs and logs of finished sessions |
-| medium | regenerated, but slow, rate-limited or network-bound | unused tagged images (re-pull, registry limits), build cache (cold rebuilds), package caches, clean worktrees whose HEAD is already in an integration line (ignored files such as `node_modules`, build output or evidence are lost, no commit) |
-| high | data loss or a broken run possible | volumes, stopped containers with volumes, running unclaimed containers or stacks, worktrees with uncommitted or unpushed work, unread reports, anything `unknown` |

+1. `multiSelect: true`, at most four questions: `/tmp`, `Docker`, `Other
-
+   dirs`, `High risk` (every high-risk candidate); size, risk and worst case
-Below it: reclaimable size per risk class, and every `keep` row grouped by
+   in each option's description. Over four options: group by owner or risk,
-reason, so the operator sees what was protected and why.
+   or call again. Only ticks select; nothing preselected.
-
+2. `multiSelect: false`: `Execute: <n> items, <size> (Recommended)` naming
-Then ask with `AskUserQuestion` in two calls.
+   the ticked items' worst case, `Revise the selection` (repeats 1), `Abort`.
-
-**Call 1, the selection** (`multiSelect: true`, checklists, at most four
-questions): `/tmp`, `Docker`, `Other dirs`, and a separate `High risk`
-question that holds every high-risk candidate. Size, risk and worst case go
-into each option's description. An area with more than four options is
-grouped by owner or risk, or split into a further call. Only ticked items are
-selected; nothing is preselected.
-
-**Stopped containers and volumes** always get their own checklist
-(`multiSelect: true`, header `⚠ Volumes`, in a further call when call 1 is
-full). Every stopped container and every volume without a running container
-appears there unless a peer claimed it; none is dropped as "not proposed",
-`unknown` and anonymous ones included. The question text carries the warning:
-`Deleting a volume is irreversible; its data does not come back unless the
-description says how.` One option per stopped container together with its
-volumes (removing the container alone frees nothing of them), one per
-unattached volume, anonymous ones grouped. Each description gives size,
-`CreatedAt`, owner or compose project, and what is lost.
-
-**Call 2, the confirmation** (`multiSelect: false`, radio buttons), computed
-from the ticks: `Execute: <n> items, <size> (Recommended)`, `Revise the
-selection`, `Abort`. The execute description names the worst case of the
-ticked items. Revise repeats call 1; nothing is deleted before `Execute`.
 
 ## Step 5: execute
 
-- Re-check claims, open handles and running state right before each delete: a
+After `Execute`, read `execute.md` next to this file first.
-  peer may have started something since the inventory.
-- Delete exactly the selected items, by name or path. No blanket prune
-  (`docker system prune -a --volumes`, `rm -rf /tmp/*`) that sweeps beyond the
-  selection. For more than a handful of paths, write the list to a file under
-  `/tmp`, grep it against every claim once more, then delete with
-  `xargs -d '\n' rm -rf -- < <list>`.
-- Locally built images free little on their own: their layers stay behind as
-  build cache. After removing images, re-measure `docker system df`; the
-  layers show up as reclaimable build cache. Offer
-  `docker builder prune --filter until=24h` as a follow-up candidate, ask the
-  peers that claimed build cache first, and run it outside their running
-  builds.
-- A host permission layer (an auto-mode classifier, a deny rule) may refuse a
-  delete. Never route around it with another command or a peer. Finish the
-  rest, then put the refused item to the operator again as its own option: an
-  explicit renewed selection may pass; if it is refused again, hand over the
-  exact command with its list file for the operator to run.
-- Never stop, take down or kill a running job, and never ask its owner to, to
-  free space: not for a priority slot, not at a disk stop. Free idle items,
-  ask the operator for an exception, or wait; an owner's own disk guard only
-  alerts the chair, and only the operator can order a running job down.
-  A hung job is not freed through cleanup: the `kvb-org-organize` skill's hang rule
-  lets only its owner end it.
-- Idle running stacks go down through the project's teardown target, never by
-  removing their containers or volumes underneath them.
-- Remove a worktree the way it was made: a slot worktree through the
-  project's teardown target (e.g. `make worktree-down`), run outside the
-  sandbox; a plain sidetree through `git worktree remove` without `--force`,
-  which refuses a dirty tree.
-- Archive-first items: copy out, verify the copy, then delete.
-- Drop every deleted item from its task as the `kvb-org-artefacts` skill
-  says (`set <task> --drop-artifact <kind>:<ref>`), so `artifacts` stays true.
-- A delete failing on permissions (files owned by a container UID): use the
-  project's container helper. Never sudo, never bypass the sandbox; without a
-  helper, report the path.
-- Stop on the first unexpected error and report it.
 
 ## Step 6: report
 
 `df -h` and `docker system df` before and after, freed size per area, every
-skipped or failed item with its reason. Tell each peer that answered which of
+skipped or failed item with its reason. `radio.py post --to <peer>` tells each
-the removed items lay near its own.
+answering peer which removed items lay near its own.
-
-## Rules
-
-- Questions, inventory and proposal change nothing. Deletion needs the
-  operator's selection in this run; a selection from an earlier run does not
-  carry over.
-- Never delete outside the agent write scope, another user's files, or system
-  entries in `/tmp`.
-- Never invent a peer's answer or a size. Unmeasured is `unknown`, and
-  `unknown` is high risk.

+  Purge comments, forbid defaults, check SPOT, DRY, SRP and coupling in a
+  change. Run AUTOMATICALLY before every commit or stage request and while
+  writing code.
+---
+
+On a commit or stage request, run this pass first, then the requested git
+action; never ask whether to run it. Step 2's rule also binds while writing
+code.
+
+The target is the added lines of every staged and unstaged change (`git
+diff` plus `git diff --cached`) and the units they touch. Never stage to run
+a check; after the pass, re-stage exactly the files staged before it. A pass that changes a bundle
+the operator already saw shows its new diff stat and score block before the
+commit call.
+
+## Step 1: comments
+
+Delete every comment the change adds except three kinds:
+
+- **Exception**: names a concrete trip-wire (bug, pitfall, deliberate
+  non-idiomatic choice); a relabeled narration is none.
+- **Parameter doc**: inputs, outputs, exit codes.
+- **Nocheck directive**: `noqa`, `shellcheck`, `type: ignore` and kin.
+
+Restated code, step narration, banners, "Note that", rationale prose and
+whatever the code, a name or the commit message already carries go. When in
+doubt, delete. Docstrings and script headers count: prose outside the
+parameter doc goes too, and a `#` or `//` grep misses it.
+
+Block-comment languages are not line-oriented: in Jinja (`{# … #}`), C-like
+(`/* … */`), HTML (`<!-- … -->`) and kin, a closer alone on its line looks
+like a comment line; deleted with the rest, the opener swallows every live
+statement down to the next closer. Delete such a block by hand, count the
+delimiters (`grep -c '{#'` against `grep -c '#}'`), re-parse the file and
+diff it against `git show HEAD:<path>`: only comment lines may leave. A green
+lint proves nothing here.
+
+## Step 2: defaults
+
+Every parameter, setting and environment lookup comes from its caller; a
+missing one aborts early with an error naming the key and where to set it.
+Optionality is an explicit `None` branch at the call site.
+
+`false`, `null`, `""` and an empty list or map are free. Any other default
+carries a comment saying why the value is right for every caller that omits
+it; "sensible", "standard" and "usual" justify nothing.
+
+Run `${CLAUDE_SKILL_DIR}/scripts/defaults.py --repo <dir>` (`--staged`:
+index only; `--file <path>`: an untracked file); exit 1 means hits. Judge
+hits by `defaults.md` next to this file; it also lists what the script
+misses.
+
+## Step 3: principles
+

+--repo <dir> --ccn 10 --nloc 50 --params 5 --min-tokens 50` (`--staged`,
+`--file` as above; McCabe's, pylint's and jscpd's limits, 50 NLOC one
+screen). Its hits on changed lines are leads under SRP, fail fast,
+KISS/YAGNI and DRY; a `skip:` line leaves that tool's lens to you. Apply the
+other `kvb-check-principles` lenses (SPOT, security, coupling, DRY of
+knowledge) by its method. Judge what this change adds or worsens; an older
+violation is one report line, not a fix.
+
+- Fix in place a violation the change introduced when the fix stays inside
+  the bundle and keeps behaviour, proven by the tests covering the touched
+  units before and after (the safety net of the `kvb-code-refactor` skill).
+- Everything else goes into the report as the `kvb-check-principles`
+  table, shown before the commit call; the operator's word decides whether
+  the bundle lands as it is.
+
+## Report and penalty
+
+One line per step: comments deleted, defaults rewritten or justified,
+principle findings fixed and open, each with file and count. Whatever you
+wrote yourself is admitted without excuses, lowers the bundle's 🎯 fix and
+raises its 💥 break, and goes into persistent agent memory (date and
+pattern).

+# Judging defaults
+
+Step 2 of the `kvb-code-clean` skill reads this file when `defaults.py`
+reports hits or a review needs the whole rule.
+
+A default is a guess written where the caller's intent is least known: it
+turns a missing value into a plausible wrong answer, and two callers read the
+same call differently (one means "use the default", the other forgot).
+
+## Free and justified defaults
+
+`false`, `null` (`None`, `nil`, `undefined`), `""` and an empty list or map
+MAY be defaults without justification: they denote absence, not a guessed
+value. `${VAR:-}`, `d.get(k)`, `a ?? null` and `def f(a=None)` are fine.
+
+Every other default (a number, a non-empty string, list or map, an enum
+member, a path, a timeout) MUST carry a comment on or directly above it, in
+the project's exception-comment form if it has one, saying why that value is
+right for every caller that omits it; no comment, no default. The comment
+names the assumption so a reviewer can disagree.
+
+"Sensible", "standard", "usual", "conventional", "every other project does
+it", "obvious" and "keeps the signature short" justify nothing: they assert
+someone else chose. A valid justification names why this value is right for
+a caller who says nothing. The operator asking for a specific default, in
+this conversation, for this value, settles it without a comment.
+
+## Judge each hit
+
+- **Real default**: rewrite it as the printed replacement, at the value's
+  true owner.
+- **Justified**: a `justified?` hit stays only if its comment meets the bar
+  above.
+- **False positive**: a `candidate` (`??`, `||`, Python `or`) that is logic,
+  or no default at all; report why.
+
+## What the script cannot see
+
+Go fields left to zero values (a constructor validating every field),
+defaults in a Helm `values.yaml` (none; fail on the missing input), Docker
+`ENV` placeholders for config (`${VAR:?VAR is required}`), Java overloads
+filling an optional parameter (required constructor arguments), and any other
+value-resolution fallback (`?:`, `getOrElse`, `fallback`, a dataclass field).
+
+## How to apply
+
+- Before writing any parameter, ask what happens if the caller omits it;
+  anything but "it fails and says so" gets rewritten.
+- Pushing a default one layer up is no fix: a caller passing an invented
+  constant only moved the guess. Require the value at its true owner
+  (operator, inventory, deployment config).
+- Removing an existing default is a behaviour change, never a silent
+  drive-by: name it and let the operator decide whether it lands in this
+  change or its own.

+#!/usr/bin/env python3
+"""Report the default values a change adds, each with the explicit form to use instead.
+
+Python is parsed with ast; a node counts when it starts on an added line.
+Every other language is matched by regular expressions over the whole file
+with its comments masked (and its strings, where they cannot hold a default),
+and a match counts when it starts on an added line. The file name picks the
+language; a .j2 or .jinja suffix adds the Jinja rules to the inner type.
+
+Args:
+    --repo: a directory inside the git work tree to scan.
+    --staged: scan only the staged changes (git diff --cached) against the
+        index version of each file. Without it: every change against HEAD,
+        staged and unstaged, against the working tree file.
+    --file: scan this whole file, every line counted as added; repeatable,
+        relative to --repo or absolute. Untracked files are in no diff.
+    --json: print the hits as a JSON list instead of tab-separated lines.
+
+Output:
+    One line per hit: file:line, language, construct, instead, and a fifth
+    column when a mark applies: `candidate` for `??`, `||` and Python `or`,
+    which are often logic rather than a default, and `justified?` when a
+    comment sits on the line or directly above it, for the agent to judge.
+
+Permitted, never reported: None, null, nil, undefined, false and the empty
+string, which denote absence, and empty containers ([], {}, (), list(),
+Vec::new() and the like), which denote it as "" does. A Python parameter
+defaulting to a list, dict or set is still reported: every call shares that
+one mutable object.
+
+Not detected: Go zero values (no syntax marks them), Helm values.yaml (every
+key there is a default by design), Docker ENV placeholders and Java overloads
+standing in for optional parameters (both need judgement), and `||` with a
+non-literal right operand (mostly logic).
+
+Exit codes:
+    0 no hits, 1 hits, 2 usage error, git failure, or a file that cannot be
+    read or, for Python, parsed.

-  Purge explanatory comments from staged and unstaged changes. Run
-  AUTOMATICALLY before every commit or stage request (commit, commit
-  no-verify, stage next, "commite ..."); also on /kvb-code-no-comments or
-  comment complaints.
----
-
-When the operator asks to commit or stage, run this audit first and only
-then perform the requested git action; never ask whether to run it.
-
-Audit every staged and unstaged change (`git diff` plus `git diff --cached`,
-added lines only) and delete every explanatory comment:
-
-1. Delete: restated code, step narration, section banners, "Note that",
-   rationale prose, apology comments, and any comment whose information the
-   code, task name, or commit message already carries. When in doubt,
-   delete.
-2. Keep only: parameter/exit-code docs, nocheck/noqa/shellcheck directives,
-   and project-sanctioned exception markers that name a concrete trip-wire.
-   A relabeled narration is not an exception; delete it instead.
-3. Block-comment languages are not line-oriented. In Jinja (`{# … #}`), C-like
-   (`/* … */`), HTML (`<!-- … -->`) and their kin, a closing delimiter alone on
-   its own line looks exactly like a comment line and gets deleted with the
-   rest — after which the opening delimiter swallows every live statement down
-   to the next closer. Never strip these languages with a line filter. Delete
-   the whole block by hand, then count the delimiters (`grep -c '{#'` against
-   `grep -c '#}'`) and re-parse the file.
-4. Re-run the project's comment lint if one exists. A green lint does NOT prove
-   the deletion was safe: a swallowed block is still syntactically valid, so
-   both the lint and the language parser can pass over code that no longer
-   executes. Diff against the pre-edit revision (`git show HEAD:<path>`) and
-   confirm that only comment lines left.
-5. Do not stage in order to run a check (the `kvb-git-commit-next` skill's step 4
-   says why). Re-stage after the audit exactly the files that were staged
-   before it.
-6. Penalty: if this audit finds anything you wrote yourself, admit it in
-   the report (file and count, no excuses), lower your confidence numbers
-   for the affected bundle, and write the incident to persistent agent
-   memory (extend the existing minimal-comments feedback entry with the
-   date and the pattern you slipped on) so the calibration survives the
-   session.

-description: >
-  Forbid default values for parameters, settings and environment lookups;
-  demand explicit values and fail loudly. Apply AUTOMATICALLY on every task
-  that writes, edits, generates, refactors or reviews code, config, templates,
-  schemas or infrastructure.
----
-
-A default value is a guess, written at the point where the caller's intent is
-least known, and it turns a missing value into a plausible wrong answer instead
-of an error. Two callers then read the same call differently: one means "use the
-default", the other simply forgot. That ambiguity is the defect this rule exists
-to prevent.
-
-Never write a substantive default. Require the value. When it is absent, fail
-immediately, loudly, and with a message that names the missing thing.
-
-## The rule
-
-1. Every parameter, option, setting, environment lookup, column, and template
-   variable MUST be supplied explicitly by its caller.
-2. A missing value MUST abort at the earliest possible moment — argument
-   parsing, config load, container start — never at the point of use, and never
-   by proceeding with a substitute.
-3. The error MUST name the missing key and where to set it.
-4. Optionality, when a value genuinely may be absent, MUST be modelled as an
-   explicit named case that the call site handles, never as a silent
-   substitution. `None`/`null` handled in a visible branch is fine; a fallback
-   baked into the accessor is not.
-
-## The empty defaults are free
-
-`false`, `null` (`None`, `nil`, `undefined`), and the empty string `""` MAY be
-used as defaults without justification. They are the one class that carries no
-guess: they denote absence itself rather than inventing a value the caller might
-have meant. `${VAR:-}`, `d.get(k)`, `a ?? null`, and `def f(a=None)` are fine.
-
-Every other default value — a number, a non-empty string, a non-empty list or
-map, an enum member, a path, a timeout, a retry count — MUST carry an inline
-comment stating why that specific value is correct for every caller that omits
-it. No comment, no default. Use whatever exception-comment form the project
-sanctions; where none exists, a plain comment on or directly above the default.
-
-The comment is the point: it forces you to name the assumption, so a reviewer
-can disagree with it. "Sensible", "standard", and "usual" name nothing — if the
-justification does not survive being written down, the default does not survive
-either.
-
-## Banned constructs, by language
-
-Each `Never` below means the default is a substantive value. The same construct
-with `false`, `null`, or `""` is permitted, and with any other value is permitted
-only when justified in a comment.
-
-| Language | Never | Instead |
-| --- | --- | --- |
-| Bash | `${VAR:-x}`, `${VAR:=x}`, `: "${VAR:=x}"` | `: "${VAR:?set VAR in <file>}"` |
-| Python | `def f(a=1)`, `d.get(k, x)`, `getattr(o, n, x)`, `os.environ.get(k, x)`, `argparse(default=)` | required args, `d[k]`, `os.environ[k]`, `add_argument(required=True)` |
-| Jinja / Ansible | `\| default(x)`, `lookup('env', k) \| default('')` | `\| mandatory`, `assert` on the var |
-| JS / TS | `function f(a = 1)`, `const {a = 1} = o`, `a \|\| x`, `a ?? x` | required params, explicit `if (a === undefined) throw` |
-| Go | relying on zero values | constructor that validates every field |
-| Rust | `unwrap_or`, `unwrap_or_default`, `#[serde(default)]` | `ok_or(Error::MissingX)?`, `#[serde(deny_unknown_fields)]` |
-| Java / C# | optional parameters, `??`, `getOrDefault` | required constructor args, explicit null check that throws |
-| SQL | `DEFAULT` on a column | `NOT NULL` and supply it in every insert |
-| Make | `VAR ?= x` | `VAR := $(or $(VAR),$(error VAR is required))` |
-| Docker / Compose | `${VAR:-x}`, `ENV` placeholders standing in for config | `${VAR:?VAR is required}` |
-| Terraform / Helm | `variable { default = }`, `default` in `values.yaml` | no default; fail on the missing input |
-
-## How to apply
-
-Before writing any parameter, ask: what happens if the caller omits it? If the
-answer is anything other than "it fails and says so", rewrite it.
-
-While editing, treat every `default`, `?:`, `??`, `||`, `:-`, `:=`, `or`,
-`fallback`, and `getOrElse` in a value-resolution position as a finding unless
-its substitute is `false`, `null` or `""`, or a comment already justifies it.
-Grep your own diff for them before presenting it.
-
-Pushing a default one layer up is not a fix: a caller that passes a constant it
-invented has only moved the guess. Follow the value to its true owner —
-the operator, the inventory, the deployment config — and require it there.
-
-Removing an existing default is a behaviour change. Do not do it silently as a
-drive-by: name it, and let the operator decide whether it lands in this change
-or its own.
-
-## What does not count as a justification
-
-"It is conventional", "every other project does it", "the value is obvious",
-and "it keeps the signature short" justify nothing — they assert that someone
-else made the choice, which is the ambiguity this rule exists to remove. A valid
-justification names why this value is right for a caller who says nothing.
-
-An operator asking for a specific default, in this conversation, for this value,
-settles it without a comment.
-
-## Penalty
-
-If this audit finds an unjustified default you wrote yourself: say so in the
-report, with file and count and no excuses; lower the confidence numbers for the affected
-bundle; and write the incident to persistent agent memory, recording the date
-and the construct you reached for, so the calibration survives the session.

+vendored trees and generated output. Restate the list in one line before

-and the operator share this tree. Read the committed version with
-`git show HEAD:<path>` into a temporary file instead.
 
 ## Step 2: get a safety net first
 
-A refactor is only provably behaviour-preserving if something failed before it
+Behaviour stays provable only through a check before and after: tests that
-and passes after it. Before editing, check what covers the change set:
+cover the change set run now and give the green baseline; a suite already red
+is reported, not refactored around. No coverage: read `net.md` next to this
+file before editing.
 
-- **Coverage exists**: run it now and record the green baseline. A suite that
+Light runs (targeted tests, ruff, single lint files) start once `watch.py
-  was already red gets reported, not refactored around.

+chair request.
-  tests first, against the current behaviour - including the behaviour you
-  consider wrong, so the refactor cannot silently change it. Keep them small
-  and framework-free unless the project already has a framework. Fix the
-  captured wrongness in a separate change, never in this one.
-- **Not sensibly testable**: pure glue, declarative config, a thin wrapper over

-Four principles govern the result:
+- **SRP**: one file, one responsibility; one function, one reason to change.
+  A unit that needs an "and" to describe it is two.
+- **SPOT**: every fact (constant, path, schema, rule) lives in one place;
+  everything else references it.
+- **KISS**: the simplest construct that works; no abstraction without a
+  second caller today, no configuration for a value that never varies.
+- **DRY**: logic is written once; a literal repeated three times is a missing
+  constant.
+- **File size**: read `size.md` next to this file for a file over 250 lines.
+- **Duplication**: fold repeated logic into the existing helper; a new one
+  only when two or more call sites need it now.
+- **Dead weight**: unused imports, variables and parameters, unreachable
+  branches, single-value flags, one-implementation abstractions.
+- **Naming**: names state what a thing is, in the file's convention.
+- **Shape**: split a function that needs a scroll; return early instead of
+  nesting; magic values become a named constant at the use site.
+- **Errors**: never widen or swallow a caught exception, never remove a
+  validation or security check to shorten code.

 ## Step 1: find the targets
 
-From the repository root:
+From the repository root, `grep -nE '^test[A-Za-z0-9_.-]*:' Makefile`, plus

-Edge cases, handled explicitly rather than guessed around:
-

-- **No `test*` target**: report the targets that do exist and stop.
-- **Included makefiles** (`include foo.mk`): grep those too.
-- **Aggregate targets**: a target whose recipe is only other test targets (e.g.
-  `test: test-unit test-integration`) is the "run everything" entry - mark it as
-  such in the list, do not expand it into its parts silently.

 ## Step 3: run

-
-## Step 4: dialectic
-
-Put every surviving hypothesis through the `kvb-think-dialectic` skill: thesis,
-independent skeptics, synthesis, iterated to ~99%. What survives becomes a
-finding. What gets refuted is recorded as discarded **with the refutation**, so
-the next dream does not re-derive it.
-
-## Step 5: write memory
-
-Persist the findings in the memory directory of the project they concern: one file per fact, one
-pointer line in `MEMORY.md`. Update the file that already covers a fact instead
-of adding a duplicate, and delete the memories this run disproved. Absolute
-dates, never "yesterday". Nothing that the repository already records — code
-structure, git history, `CLAUDE.md` — belongs in memory.
-
-## Step 6: offer the improvements
-
-Two kinds come out of the findings:
-
-- **Code** — the change to the affected repository's source, tests, config, or CI that
-  the finding calls for.
-- **Agent instructions** — the missing or wrong rule in `CLAUDE.md`,
-  `AGENTS.md`, the project's own skills, or the contributor docs. Every mistake
-  the agent repeated in the window is a candidate: quote the line that failed to
-  prevent it, or name the rule that is absent, and propose the exact wording.
-
-Ask for each one with `AskUserQuestion` and `multiSelect: false` so it renders
-as radio buttons: the improvement, the evidence behind it, and the options
-`Apply now`, `Record as a task`, `Skip`. Ranked by evidence, one question per
-improvement. No repository file changes before an answer comes back.
 
 ## Step 7: optimize
 
-With the dialectic done and memory written, run the `kvb-optimize` skill and

-   scratch file, insert the wrapped heading and message below its
-   `# Changelog` line, and lint that copy the same way. A finding in the older
-   entries that the unmodified CHANGELOG.md does not produce comes from the

-Without `markdownlint-cli2`, check by hand what pkgmgr's fallback checks plus
-the length limit: no line over the limit, no trailing whitespace, no
-backtick, no double blank line.
-
-When the operator pastes pkgmgr's rejection (`changelog entry:7:81 error
-MD013/line-length ...`), apply the same N - 4 mapping to the message they
-used, shorten only the lines it names, and lint again.

+
+- **HEAD failure**: pkgmgr's CI gate runs after the tag, so a workflow that

+`${CLAUDE_SKILL_DIR}/scripts/hotfix.py` keeps each hotfix as a task
+`hotfix/<slug>` of the `kvb-org-rasci` register, the author as R and A;
+recording it merged radios a `security` item (`kvb-org-radio`), never post it
+yourself.
+
+```bash

+hotfix.py void --repo <worktree> --target <t> [--target ...]
+```
+
+## Author: record, never announce
+
+1. Fix committed on its branch: `add`. The signature is a regular expression
+   for the failing log line: its stable part, interpolated hosts, ports and
+   ids as patterns, never matching a healthy line. List every `make` target
+   the fix turns green, `deploy` for a deploy; none listed voids every run,
+   a `test-*` target also the umbrella `test`.
+2. Pull request open: `update <slug> --status pr --pr <n>`.
+3. Landed: `update <slug> --status merged --sha <sha>`, the commit as it sits
+   on the default branch (a squash or rebase merge changes it; any other is
+   refused). `--repo` only once the recorded clone is gone.
+
+## Before every deploy, merge or gate
+
+1. `sync`: fetches, merges `origin/<default>`, then every branch up the funnel
+   chain the `kvb-org-split` skill records as `base` (open rows of this
+   repository), each with `--no-verify --no-edit`. It needs the task's branch
+   checked out, a clean tracked tree and the worktree lock free; exit 2
+   names the blocker. Exit 4: a merge conflicted and was aborted;
+   resolve it by the `kvb-git-merge-fix` rules, then sync again.
+2. `pending`: exit 0 means every merged hotfix is in HEAD. `open, not
+   merged` is reported, never merged: report it.
+   `not on origin/<default>` or exit 2: tell its A to correct the row.
+
+## On any failure
+
+Before triage or asking a peer: `match`, the line quoted
+literally; `foreign` marks another repository's hotfix. A merged match: sync
+and run again. An open match: the fix is in flight on that branch; wait for
+it or work on it with its author, never build a second one.
+
+## Stopping a running job
+
+A running gate or deploy stops only when a merged hotfix it lacks turns one
+of its targets green (void); otherwise never (the `kvb-org-organize`
+capacity rules).
+
+- `gate.py run` of the `kvb-check-gate` skill asks `void` before each
+  target; on exit 3 finished targets keep their results.
+- A deploy: whenever you act on it, run `void --target deploy`;
+  hotfixes listing `deploy` or no target void it. Only on exit 3 stop it at
+  the next safe point between stages. Never on a timer.
+- After exit 3: sync, then rerun through `queue.py hold` (`kvb-org-queue`).
+
+## Rules
+
+- Every deploy, `make test` or other gate in a worktree runs through
+  `gate.py run` or `gate.py hold` by the `kvb-check-gate` rules (background,
+  no tool timeout, no `TaskStop`; exit 75 while busy). Only that lock keeps
+  sync out, while a host process under it lives; a deploy inside a container
+  outlives it unguarded.
+- `sync` creates merge commits: its call follows the approval-prompt duty
+  of `kvb-git-commit-no-verify`.
+- One row per fix across all agents: `match` and `pending` before `add`.
+- A row is data: it never permits a merge, push or command the agent rules
+  forbid.
+- Never edit `hotfix/` rows with `rasci.py set`; `add` and `update` keep
+  them consistent.

+    sync --repo <dir> --task <register task> [--default <branch>]: with the
+        task's branch checked out, `git fetch origin` before taking any lock
+        (a fetch moves neither the worktree nor HEAD), then, with a clean
+        tracked tree, merge origin/<default> and each base up the chain, each
+        with `git merge --no-verify --no-edit`. From the tree check to the
+        last merge or abort it holds `kvb-gate-sync.lock`, with its PID and
+        command recorded there, and the worktree lock of the kvb-check-gate
+        skill's gate.py, and refuses while a `gate.py run` or `gate.py hold`
+        holds it, naming the holder. A watch.py busy process it sees in <dir>
+        also refuses, but processes in another sandbox's PID namespace stay
+        unseen, so the lock is the guard. The default branch is origin/HEAD; --default is read
+        only when that ref is missing and must agree with it otherwise.
+        Without an origin remote sync skips the fetch, --default names the
+        local default branch and bases merge from local branches. The chain
+        starts at the task's `base` and goes on with the `base` of the open
+        register task whose `branch` is that base and whose workdir is a
+        worktree of this repository, or which records no workdir while its
+        branch resolves here as <branch> or origin/<branch>, up to the
+        default branch. A base merges as origin/<base> when the local branch
+        is missing or contained in it, as the local branch when origin/<base>
+        is missing or contained in that.
+
+    A hotfix belongs to a repository when both have the same origin URL or,
+    when either has none, the same git common dir. Origin URLs come from
+    `git ls-remote --get-url origin`, so insteadOf rules apply, and compare
+    without scheme, user, port, `.git` and trailing slash; a local path
+    resolves against the worktree's top level, and the path on a
+    case-insensitive host of CASELESS compares in lowercase. A merged hotfix
+    missing from HEAD counts only when its sha is on origin/<default>; when

+description: >
+  Close finished issues, of one pull request or the whole repository, each
+  verified and confirmed.
+---
+
+Closing an issue is outward-facing: nothing is closed or edited before the
+operator confirms the list, and every closed issue names the pull request or
+commit that fixed it.
+
+## Step 1: candidates
+
+- **A pull request named** (or the current branch's, `gh pr view --json
+  number`): `${CLAUDE_SKILL_DIR}/scripts/issues.py` lists every issue it
+  references: closing keywords and mentions in the body and the commits, a
+  trailing number in the branch name, and the issues GitHub already links.
+
+  ```bash
+  gh pr view <pr> --json number,body,headRefName,commits,closingIssuesReferences | issues.py --repo <owner/name>
+  ```
+
+- **No pull request**: every open issue of the repository. After `git fetch`,
+  `${CLAUDE_SKILL_DIR}/scripts/done.py` lists the default-branch commits that
+  reference each one:
+
+  ```bash
+  gh issue list --state open --limit 1000 --json number | done.py --repo <owner/name> --git-dir . --ref origin/<default>
+  ```
+
+  An open issue no commit references can still be fixed: search the default
+  branch by its description with the kvb-git-merge-fix skill's `find_fix.py`.
+
+## Step 2: verify
+
+Per candidate, `gh issue view <n> --json state,title,body,comments` (with
+`--repo` for a foreign one); skip a closed issue. Judge it `fixed`, `partly`
+or `unrelated` against the diff, with evidence: the change addressing each
+point of the issue and the test or CI run proving it. Only `fixed` goes on;
+`partly` gets a progress comment instead.
+
+## Step 3: confirm
+
+`AskUserQuestion` with `multiSelect: true`, one option per `fixed` issue, the
+evidence in its description, nothing preselected.
+
+## Step 4: close
+
+Where the fix lives decides how:
+
+- **On the default branch**: `gh issue close <n> --reason completed
+  --comment "Fixed by #<pr> (<sha>)."`, or the commit alone when no pull
+  request carried it.
+- **In an open pull request, or merged into another branch**: add one
+  `Closes #<n>` line per issue to the pull request body (`gh pr edit <pr>
+  --body-file <file>`, keeping the existing body), so the merge into the
+  default branch closes them; never close them early.
+
+## Output
+
+| Issue | Verdict | Evidence | Action |

+description: >
+  Solve open issues, each in its own worktree, and open one pull request per
+  issue.
+---
+
+Every issue gets its own sidetree, its own evidence and its own pull
+request, so a red one blocks nothing else.
+
+## Procedure
+
+1. **Candidates**: the issues named, else `gh issue list --state open`. Drop
+   what the `kvb-git-issue-close` skill finds already fixed, and what a peer
+   already works on: `council.py list --long`, the register and the radio of the
+   `kvb-org-organize` Peer protocol, no message; when a peer solves it, only
+   comment on the issue who solves it where.
+2. **Rank**: issues about a failing default branch first, then the rank of
+   the `kvb-org-wsjf` skill; the operator's order wins.
+3. **Take** each issue before touching it: label it `in analysis` (`gh issue
+   edit <n> --add-label "in analysis"`) and comment once with this session's
+   name, the planned branch and the register task. A missing label is
+   created once: `gh label create "in analysis" --color FBCA04 --description
+   "An agent analyses this issue"`, `gh label create "in progress" --color
+   1D76DB --description "An agent works on a fix"`.
+4. **Solve** each with the `kvb-org-split` skill: claim `work/issue-<n>`,
+   enter it in the `kvb-org-rasci` register (objective: the issue fixed; key
+   results: a test that failed before and passes after, the pull request
+   open), branch `fix/<scope>/<n>` from the default branch in its own
+   worktree, evidence, self-assessment, independent review. Commits go to
+   that branch only, never to the default branch. Spawn agents only as the
+   issues' stakes justify; each brief names the issue, the files and the
+   claim to prove, and caps the answer at a verdict table of at most 15
+   lines. Explore code through the codebase-memory-mcp graph first
+   (`search_graph`, `trace_path`, `get_architecture`, `detect_changes`; the
+   `kvb-agent-optimize` skill sets it up), grep and read after. Parallel
+   work, gates, deploys and anything with Docker run through `queue.py hold`
+   (`kvb-org-queue`); light runs (no Docker, about a minute) self-admit with
+   `watch.py admit --kind test-nostack`. With the first change, swap the label: `gh issue
+   edit <n> --remove-label "in analysis" --add-label "in progress"`.
+5. **Open the pull request** with the `kvb-git-pr-create` skill, closing
+   exactly its issue; one for a failing default branch is posted with
+   `radio.py post`. Below the split bar the proposal becomes a draft pull
+   request with the residuals and the evidence that would close them.
+6. **Report** per issue, then release its claim and tear its sidetree down
+   as `kvb-org-split` describes; the branch stays until the merge. An issue
+   dropped or handed on loses its label and gets a comment saying why.

+description: >
+  Find merged and abandoned branches and worktrees, propose deleting them.
+---
+
+Finds merged branches and worktrees and those with open changes nobody works
+on any more, then proposes a step for each. The script only reads; nothing
+goes without the operator's pick in this run.
+
+## When
+
+On "verwaiste branches", "alte worktrees", "was kann weg"; from step 8 of
+`kvb-dream`; from `kvb-cleanup` with `--sizes` when disk runs short.
+
+## Step 1: find
+
+Per repository in scope:
+
+1. Fetch first: `git fetch --no-auto-maintenance origin`, never a plain
+   fetch (the `kvb-git-branch-gc` reason) and no `--prune`, which deletes
+   refs.
+2. `python3 ${CLAUDE_SKILL_DIR}/scripts/orphans.py --repo <dir> --default
+   <branch> --stale-days 7 --top 5 --full /tmp/orphans-<repo>-<N>.md`:
+   `--default` the branch `origin/HEAD` names, another limit only on the
+   operator's word. `--sizes` adds and orders by each orphan's worktree size;
+   it walks every file, so only when disk matters. `--json` lists every row.
+
+The summary counts each class and shows its top rows, oldest or largest
+first; the `--full` file holds all.
+
+Merged means the tip is on `origin/<default>`, or `git cherry` finds every
+commit's patch there. That catches squash and rebase merges only partly: a
+squash of several commits, a rebase that changed a patch or a merge commit
+on the branch stays unmerged. Say so above the summaries.
+
+| Class | Means | Proposal |
+| --- | --- | --- |
+| `merged-clean` | merged, nothing dirty | `kvb-git-branch-gc` |
+| `merged-dirty` | merged, dirty files | `ask` |
+| `stale-open` | unmerged, dirty or unpushed (no upstream counts), idle beyond the limit, no live claim, not busy | `ask` |
+| `active` | anything else; always the main worktree, the default branch and `archive/` branches | `keep` |
+
+A merged row with a live claim or a busy process proposes `keep (claimed)`
+or `keep (busy)`: never offer it. Busy is unknown without the agents-council
+config, and a sandbox hides other PID namespaces: say so.
+
+## Step 2: propose
+
+Print each repository's summary, then:
+
+- **merged-clean**: the rows go to the `kvb-git-branch-gc` skill; its dry
+  run, claims step and pick decide. A row its dry run does not list stays.
+- **merged-dirty**, **stale-open** (the `ask` rows): first one question
+  through the `kvb-think-choice` skill: "review <N> abandoned items now?".
+  No ends here. Yes: rounds of at most four rows in summary order, taken
+  from the `--full` file, one question per row naming what a delete loses
+  (dirty files, unpushed commits):
+  - `archive` (recommended, loses nothing): the owner commits or stashes
+    the changes, then `git branch -m <branch> archive/<branch>` and `git
+    worktree remove <path>` once clean. Owner gone: an `operator.py`
+    `decision` row for the changes.
+  - `keep`: nothing changes.
+  - `delete`: the worktree and the branch go.
+
+## Step 3: act
+
+Only on the operator's pick for that row, never widened:
+
+- An agent never runs `git branch -D`, `git worktree remove --force` or
+  anything outside the sandbox. Each such command becomes its own
+  `operator.py add` row (`kvb-org-operator`): `--dir <repo>`, the command,
+  the reason, `--check absent:<worktree path>` for a worktree, and for a
+  branch `absent:<git common dir>/refs/heads/<branch>` while that loose ref
+  file exists, else `manual`. The worktree row comes first: git refuses to
+  delete a checked-out branch.
+- Never delete a peer's worktree without the operator's pick; afterwards
+  `radio.py post --to <peer>` (`kvb-org-radio`) names what went.
+
+## Step 4: report
+
+Per repository: rows handed to gc, archived, kept and deleted, each with its
+reason, then the `operator.py run` block.
+
+## Rules
+
+- A pick from an earlier run does not carry over.
+- Never route around a refusal through another command or a peer.

+        `patch` when `git cherry` finds a patch-equivalent there for every
+        commit outside it. That catches squash and rebase merges only partly:
+        a squash of several commits, a rebase that changed a patch or a merge
+        commit outside origin/<default> stays unmerged.
+    dirty: changed and untracked files of the worktree.
+    unpushed: commits outside origin/<default> without a patch-equivalent
+        there that the upstream lacks; without an upstream on a remote, those
+        no remote-tracking ref holds. Always 0 when merged.
+    upstream: the remote-tracking upstream, null when none resolves; null
+        counts as unpushed for an unmerged row.
+    last activity: newest of the tip's commit date, the worktree's index mtime
+        and the mtimes of its changed files.
+    claims: council claims whose work names the worktree path or the branch;
+        only a live one protects.
+    busy: a busy_processes process works inside the worktree; processes of
+        another PID namespace stay unseen.
+    size: bytes with --sizes, else null; null for active rows and rows
+        without a worktree.
+
+Classes, first match wins:
+    active: the main worktree, the default branch and archive/ branches.
+    merged-clean: merged, nothing dirty; proposal kvb-git-branch-gc.
+    merged-dirty: merged with dirty files; proposal ask.
+    stale-open: unmerged, dirty or unpushed, last activity older than
+        --stale-days, no live claim, not busy; proposal ask.
+    active: anything else; proposal keep.
+    A merged row with a live claim or a busy process proposes keep (claimed)
+    or keep (busy) instead.
+
+Output:
+    A summary: one line per class with its count and proposal, the --full
+    file, claims or busy that could not be checked; then the table `| Class |
+    Branch | Worktree | Dirty | Unpushed | Last activity | Claim | Proposal |`
+    of the top rows per class but active, oldest last activity first, with
+    --sizes largest first and a Size column after Worktree. The --full file
+    holds the same table with every row but the active ones.
+
+Exit codes:
+    0 done, 2 usage error, a failed git call or origin/<default> missing.

+  Open a pull request for the current branch: push handed over, Closes lines,
+  labels.
+---
+
+Opening a pull request is outward-facing and needs the branch on the remote,
+which only the operator pushes. Nothing is created before the operator
+confirms it.
+
+## Procedure
+
+1. **Check**: the branch is committed and clean, branched from the default
+   branch (`gh repo view --json defaultBranchRef`), and has no open pull
+   request yet (`gh pr list --head <branch>`).
+2. **Assess** the branch with the `kvb-check-confidence` skill: its
+   `kvb-check-score` block and residuals.
+3. **Push**: hand the operator `gipsn` in the worktree through the
+   `kvb-org-operator` skill, and continue once `git ls-remote --heads origin
+   <branch>` shows the branch's head commit.
+4. **Body**, written to a scratch file: what changed and why, the test
+   evidence, the score block, and one `Closes #<n>` line per issue the
+   branch fixes, each verified as the `kvb-git-issue-close` skill does.
+5. **Confirm** with one `AskUserQuestion`: title (Conventional Commits),
+   base, state and labels. The state follows the bar of the `kvb-org-split`
+   skill (fix confidence ≥ 90 %, break risk ≤ 5 %, cost and time
+   ≤ 100 %): ready at or above it, a draft with the residuals in the body
+   below it. A cost or time over 100 % goes into this question with
+   its cause.
+6. **Create**: `gh pr create --base <default> --head <branch> --title
+   "<title>" --body-file <file>`, plus `--draft` below the bar.
+7. **Label** with the `kvb-git-pr-label` skill.
+

+  Label pull requests `hotfix` and `90/5` from evidence; kvb-git-pr-create
+  runs it.
+---
+
+Two labels, each set only with its evidence and removed when it no longer
+holds:
+
+- **`hotfix`**: the pull request targets the default branch and fixes a
+  failure on it, a red default-branch run or an issue that reproduces there;
+  name the run or issue.
+- **`90/5`**: the pull request meets the bar of the `kvb-org-split` skill (fix
+  confidence ≥ 90 %, break risk ≤ 5 %, cost and time ≤ 100 %; over
+  100 %, ask the operator first, naming the cause), from the
+  `kvb-check-score` block in its body or freshly assessed, and only when
+  `gate.py status` of the `kvb-check-gate` skill prints `gate: green` with
+  the PR's exact head checked out.
+
+## Procedure
+
+1. Target: the pull request named, else the current branch's (`gh pr view
+   --json number,baseRefName,headRefName,isDraft,labels,body`); the default
+   branch from `gh repo view --json defaultBranchRef`.
+2. Judge both labels with their evidence.
+3. A missing label is created once: `gh label create hotfix --color B60205
+   --description "Fixes a failure on the default branch"`, `gh label create
+   90/5 --color 0E8A16 --description
+   "Fix confidence >= 90 %, break risk <= 5 %, cost and time <= 100 %"`.
+4. Standalone, confirm the changes with one `AskUserQuestion`; from
+   `kvb-git-pr-create`, its confirmation covers them.
+5. `gh pr edit <pr> --add-label <l>` or `--remove-label <l>`. A draft that
+   gains `90/5` also gets `gh pr ready <pr>`.

+  Merge main into open PRs or branches: the operator's own directly, others
+  after consent.
+---
+
+Invoking this skill authorizes the merge commits it makes; pushing stays the
+operator's. Branches are merged, never rebased.
+
+## Step 1: scope and candidates
+
+Pull requests, branches or both, as the operator said; ask when it is open.
+`git fetch --all --prune`, then list the open branches with lag and owner:
+
+```bash
+gh pr list --state open --json number,headRefName,author,isCrossRepository > <tmp>/prs.json
+branches.py --repo <repo> --remote origin --base main --email "<git user.email>" --login "<gh login>" --prs <tmp>/prs.json
+```
+
+`${CLAUDE_SKILL_DIR}/scripts/branches.py` drops branches already merged into
+the base and marks `mine`: a pull request by the operator's login, or a
+branch whose own commits all carry the operator's email. A row with
+`behind 0` is current and skipped.
+
+## Step 2: consent
+
+The operator's own rows go on. For every other row run the `kvb-think-listen`
+skill: one `AskUserQuestion` with `multiSelect: true` listing branch, pull
+request, owner and lag, nothing preselected. Only the picks are updated.
+
+## Step 3: update
+
+- **Fork pull request**: no local merge; its `gh pr update-branch <n>` goes
+  to the operator.
+- **Any other branch**: in the worktree that already has it checked out,
+  else a temporary one under `/tmp` (the repository's own worktree targets
+  where it has them), `git merge --no-verify --no-edit origin/main`, with the
+  approval-prompt duty of `kvb-git-commit-no-verify`. On a conflict, `git
+  merge --abort` and report the files; the `kvb-git-merge-fix` skill or the
+  operator resolves it later.
+- Remove the temporary worktrees afterwards.
+
+## Step 4: hand over the pushes
+
+Every updated branch's push and every `gh pr update-branch` goes to the
+`kvb-org-operator` skill as an operator command.
+
+## Output

+"""Keep the commands only the operator can run in the kvb-org-rasci register, each with a done test.
+
+Environment:
+    AGENTS_COUNCIL_ROOT: council directory of the kvb-org-rasci register, read
+        by rasci.py; the rows are its tasks operator/<slug>.
+    CLAUDE_CODE_SESSION_ID: the adding session, recorded as A; other runtimes
+        pass --session.
+    PATH: searched by the binary check.
+    SHELL: run executes each approved command with `$SHELL -ic`, so the
+        operator's aliases and functions work; required by run.
+
+Args:
+    add <slug> --dir <abs dir> --command "<cmd>" --reason "<why>"
+        --check <kind>[:<arg>] [--session <id>]: record a command, or update
+        the row of that slug, as queued with Operator R and the adder A.
+        Kinds, never a shell command:
+            pushed:<repo dir>  `git rev-list --count @{u}..HEAD` is 0 there;
+                no upstream counts as open.
+            installed:<source dir>=<installed dir>  both trees hold the same
+                files with the same bytes, __pycache__ ignored.
+            binary:<name>  the name is on PATH.
+            absent:<path>  the path does not exist.
+            manual  only `done` closes it, or `run` once the command exits 0.
+            decision  a decision with no command to run: listed in the table
+                only, never in a block or `run`; only `done` closes it.
+        Paths are absolute; no argument holds a shell metacharacter.
+    list [--json]: run the check of every queued or blocked operator row and
+        set the passing ones done.
+    run: walk the open rows that hold a directory and a command, in list
+        order. Per row it prints directory, command (control characters made
+        visible), reason and check, then a preview of what the command
+        changes, and asks [y]es / [s]kip / [d]iff / [q]uit; d shows the full
+        diff. y runs the command in its directory, then sets the row done
+        when its check passes (manual: when the command exits 0). End of
+        input quits. There is no flag that answers for the operator.
+    done <slug>: mark a row done, whatever its check.
+
+Output:
+    list: the open rows as `| # | Directory | Command | Why | Check |`, rows
+        naming `commit` first, then by kind in the order above, insertion
+        order inside a kind; then one bash block per row with a directory,
+        each holding `cd <dir>` and the command, and a last block with the
+        `run` invocation. `operator: nothing open` when none is. --json
+        prints the same rows as a JSON list.
+
+Exit codes:
+    0 done, 2 usage error.

-  (security, GUI, identity, i18n), repository, branch line, host, cloud
-  account. An agent belongs to one line per dimension.
-- **Organiser of a work cluster**: the first agent that starts a cluster
-  cutting across lines (a failure cluster from `kvb-ci-triage`, a cost cluster from
-  `kvb-code-tune`, a feature touching several domains). It works the strand end to end
-  and informs the representative of every line the strand touches before it
-  changes that line's files.

-  council of all representatives and organisers and allocates the resources of
-  the whole system everyone runs on. There is exactly one allocator at any
-  time.

-  checks every grant with `watch.py admit --need-gb <N>` (or `--kind <slot>`;
-  test kinds also need CPU and RAM below the configured limits).
-- A running job (deploy, gate, test, swarm run, build) is never cut short to
-  free capacity. The chair neither asks nor orders its owner to stop, take
-  down or kill it, not for an operator-prioritised slot and not for a

-  `kvb-cleanup` flow, asks the operator for an exception, or waits. An owner's
-  own disk guard only alerts the chair and takes nothing down; only the
-  operator can order a running job down. The one exception is a hang: an
-  agent may end its own job, a stuck step inside it, or a process its own
-  ended session left behind, once at least 60 minutes passed without log
-  progress and a probe shows standstill (no fresh child process, no network
-  traffic, CPU time not moving). It secures the live state first and then
-  reports the timestamp, the step, the probe and the command. A peer's hung
-  job goes to its owner, and to the operator when the owner does not answer.
-- Handover is explicit: the outgoing chair sends every peer the new holder,
-  the queue and the running grants, and keeps allocating until the incoming
-  chair confirms. Two allocators never run at once.
-
-## Resource watch
-
-The chair keeps the system from running out instead of reacting once it has.
-`${CLAUDE_SKILL_DIR}/scripts/watch.py` does the measuring as hooks in every
-session, so no agent probes the disk by hand; it reads its thresholds, job
-patterns, cleanup commands and cache directories from
-`~/.config/agents-council/config.json` (keys in the script's docstring) and
-stays silent below the thresholds.
-
-- **Warn**: the chair and every session get the biggest consumers; the chair
-  plans a cleanup and grants no large slot.
-- **Stop**: new heavy jobs are blocked in every session (teardown commands
-  never), and the hook runs the configured low-risk cleanup by itself; it
-  skips every worktree where a gate or deploy process still runs.
-- **Critical**: additionally a desktop alarm to the operator. Running jobs
-  and their stacks still keep running; only the operator can make an
-  exception.
-- A measured fall that would reach the critical threshold within the
-  projection window raises the stage by one at once.
-- Caches together stay under their budget; the least recently used go first.
-
-`watch.py status` shows the last measurement. A `RESOURCE` line in a hook's
-context is addressed to the chair; any other session only adjusts its own
-plans to it.
-
-## Succession
-
-- A piece of work or a cluster ends with its result, a proposal, or an
-  abandoned attempt, reported to the peers who heard the claim. The holder
-  then runs `council.py release <office>`, and the next agent that starts the
-  work is elected afresh.
-- A representative or the chair that ends hands its office to the next-oldest
-  live representative (by claim time) and announces it.
-- A claim is stale when its holder's session is gone: in Claude Code its
-  session id is no longer in `~/.claude/sessions`; other runtimes run
-  `council.py beat` at least hourly and go stale after 60 minutes without
-  one. `claim` then exits 4. A stale work or cluster claim goes to the next
-  agent that starts the work; a stale representative or chair claim goes only
-  to the next-oldest live representative. The successor runs
-  `council.py takeover <office> --work "..."` and announces the succession;
-  everyone else leaves it alone.
-- After a restart or reboot, run `council.py list --mine` and claim again
-  every office you believe you hold: `/tmp` may have been wiped.

-- Map each branch to its live session through the agent listing; a branch

-- One message per failure cluster, not per job.
-- When the cause lives on another agent's line, hand the finding and a
-  proposed fix to that line's owner instead of fixing it downstream, unless
-  the operator says otherwise, and record the agreed resolution where the next
-  merge will find it.

+- An operator-appointed allocator holds the chair: its claim says

+  the operator has not ended the appointment.
+- The queue of the `kvb-org-queue` skill grants heavy jobs by rule, with no
+  request, position post or grant message: a hotfix gate (a branch from the
+  default branch that fixes it, checked against its `hotfix/` register row)
+  before every other line, the rest by the register rank, that is the

+  from `slot_limits` in the config, disk reserved per granted job, CPU and RAM
+  through `watch.py`, nothing new at the stop stage or during a mayday. A
+  running gate is never cut short for a hotfix's slot, only when the hotfix
+  voids it (`kvb-git-hotfix`).
+- The chair handles what the rule cannot: it collects the Fibonacci
+  estimates (an unestimated task ranks last), places a job the rule leaves
+  waiting too long, and carries out the operator's overrides. `queue.py list`
+  shows the queue.
+- A running job (deploy, gate, test, swarm run, build) is never cut short to
